How Distributed Antenna Systems Work: Whiteboard Video

Posted by Lisa MacGillivray on Thursday, June 29, 2017

If you’re generally aware that distributed antenna systems can fix poor connectivity in your building but you aren’t quite clear about how they work, we’ve got a great whiteboard video that walks you through the process.

A distributed antenna system, also known as a DAS, is a highly effective way to instantly improve cell phone coverage and radio range, especially in older buildings or reinforced locations such as stairwells, basements and garages. If you learn better by reading, our distributed antenna system guide also offers a detailed overview.

In just two minutes, the whiteboard video explains:

  • What Distributed Antenna Systems Are
  • Parts Contained in a Distributed Antenna System
  • How DAS Solutions are Custom Built and Installed

Watch the video now, or read below for more details:

What Distributed Antenna Systems Are

A distributed antenna system is a network of antennas both indoor and outdoor, along with bi-directional amplifiers, that amplifies the strength of your radio and commercial carrier signs and frequencies for more reliable in-building communications coverage.

Parts Contained in a Distributed Antenna System

A DAS is made up of: 

  • Indoor and outdoor antennas
  • Coaxial or fiber cabling
  • Hybrid couplers
  • Bi-directional amplifiers (BDAs)

The outdoor antennas capture signals that are redistributed by their indoor counterparts. The power dividers and hybrid couplers connect the antennas to the BDAs via cabling infrastructure. The BDAs then relay and amplify radio frequency, or RF, signals from private or commercial services.

How DAS Solutions are Custom Built and Installed

To function optimally, DAS solutions should be custom designed and built based on the specific building, location, and business or agency. The first step is to analyze the current radio or commercial carrier system in the building, including the bands and frequencies, as well as the areas of coverage.

Distributed antenna systems are flexible enough to be outfitted for “the smallest office or the largest hospital.” And while they’re most commonly used for cellular carriers and public safety, they can be tailored for any businesses’ in-building communications needs.  

In other words: No more “can you hear me now?”
